I was following a tutorial that adjusting camera size,
but on my Unity 5.4.2f1,
I cannot find ‘Size’ on my Main Camera properties.
On the tutorial, below the Projection, there is ‘Size’ item, but none on my Unity.
Is the name changed to another?
A perspective camera doesn’t have a size. It originates from a singular point like a pyramid and has a “field of view” angle that determines the steepness of the pyramid’s sides.
If you change projection to orthographic, you will get a size slider that adjusts the height of the orthographic “view cube”.
